"Close your boot remotely using your key fob (and retain the opening feature)
Go to Module 46 (cent convenience), coding, long coding helper and ensure byte two, bit two is ticked it says "Comfort operation: Remote control active". Then got to module 6D (Trunk Electrics), security access and enter security code "12345". Then still in Module 6D, click adaptation, channel and there are 4 options in there (among others) called "Activation using rear lid opening button in remote key - Touch function for closing". Select all four of those options, one at a time, and change the value to ACTIVE and press do it. Thats it. You still open your boot as normal - press and hold the middle button on the fob, but to close it, you can now just click the button on the remote (not a press and hold) and the boot will close and beep to warn you.
